Right Click on Track 1 event and select Item Settings> Mono(Left)ДЈ. Which is what I believe Justin described.Дў. Yeah, I came late into this post late.but was scratching my head of the pretty simple way of doing this in Reaper already. The reason I asked for clarification, is you could also easily set up some routing of the left channel to a track, the right to a diff track, which could be useful as well. I will look into the mono rendering bug, too. Step 4: select all items in Mењњhannel R, right click, Item Settings, Channel Mode: Mono (R). Step 3: select all items in Mењњhannel L, right click, Item Settings, Channel Mode: Mono (L). Step 2: label the original Mењњhannel L (optionally pan left), the duplicate Mењњhannel R (optioanlly pan right) Step 1: duplicate the stereo track (or multiple stereo tracks) right away to make REAPER more powerfull. So when Justin needs to fix it anyway he should implement some more modes like 'only left', 'only right', 'left-right', etc. So waht I think happens, it only takes the left channel and doesn't do any down mix, etc.

I don't think it is broken, it's just lacking a prober mono.

Once this is sorted out, it should be possible very easily to do what's wanted, but at present it seems to be broken in this respect. Render to stereo, you get the correct result in a stereo file. Create a new project, insert an item onto track one, pull its pan control to the right, render to mono, and you get silence. Why should that be?Д®dit - indeed, there seems to be a major bug here. Do the same with the track pan control to the right, I get a silent file. To be more specific - if I render a single track with the pan control to the left, rendering to mono, I get what looks like the correct result. You should be able to do this by duplicating the track and then doing a stem render of the tracks to mono with one panned left and the other right - except that the result seems to be one file with audio and other silent - seems to be a bug?! IMO a nice feature, the only problem is, you won't need it when recording in REAPER in the first place :D The probleme with recording mono in the first place is, that he might have run out of inputs and just used a stereo input as 2 monos and some host don't have the option to record seperate (how poor is that :D).

I'd also suggest that workaround, but if you have like 14 files, routing might be easier/quicker. I`m testing REAPER every few weeks if i could use it as my main host, but i think it will take some time till little things like this are fixed. So i have to do the obove steps 14 times! like 1 file is: kick left channel, snare right channel. Problem: i wanted to do i mix for a friend and got 14 stereo files. do the same for the dublicatet track and select mono (right) and i found a workaround myself, it goes like this: So the problem is quite clear now i think. Now you have gotten rid of the lead singing in the song (and most of the bass, but that is just a bad side effect), and you got your own karaokee track of that song. Merge the two tracks together again to a stereotrack. Split the left and right channels into separate tracks. Take any popular commercial song, import it into reaper. One clear example of usage would be the following: And I am sure this can already be done using routing but this would be more intuitive. So why would you want to do this? Well to be able to assign fx to the channels individually of course. Put the left channel wav file in one of the new tracks, and the right channel wav file in the other.Д¤. Split the Stereo wav file in two mono files representing the Left and Right channels in the original wav file.ДЈ. You now want to replace this one track with two tracks one called Guitar L and one Guitar R.Дў. You have one stereotrack called Guitar in a Reaper project recorded as a stereo wav file. Let me just try to clearify what it means just in case. Hmm, I thought when reading this that the question was quite clear, but either the question is not so clear, or I am dumb and does not understand that you all understand the question.
